From 35e03f3a0275a1ba57e432d7c948cf6f70fbb37a Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 13 Feb 2013 12:00:20 +0000 Subject: bridge: Separate egress policy bitmap Add an ability to configure a separate "untagged" egress policy to the VLAN information of the bridge. This superseeds PVID policy and makes PVID ingress-only. The policy is configured with a new flag and is represented as a port bitmap per vlan. Egress frames with a VLAN id in "untagged" policy bitmap would egress the port without VLAN header. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
